Jennifer Lopez Arrives to the Met Gala Solo, Ben Affleck Filming in L.A.

Jennifer Lopez just showed up to the Met Gala — and while she was rolling solo … we know it’s only because Ben Affleck is hard at work on the West Coast, where he’s on set.

The actress/singer made a big entrance Monday at the Metropolitan Museum of Art in NYC — where fashion’s biggest night is underway … and where J Lo, a co-chair for the event, rolled up by herself, without her hubby by her side.

No need to panic though — not only was Jen wearing a wedding band on that finger … but we’ve learned there’s a perfectly good explanation — the dude is literally filming right now.

In other words … it’s all going according to plan. And if you look at what Jen was doing last year at this very same event … not much has changed, ’cause Ben wasn’t there either.

You’ll recall … JL walked up the stairs in 2023 by herself as well. They didn’t hit the event in 2022 — the year they got hitched. On its face, it seems it just isn’t Ben’s scene … but it is his best friend’s — Matt Damon is in the building and he’s there with his own wife, smiling.

Remember … Ben and Jen were opposite coasts this weekend too — she was in New York getting ready for the gala, attending a pre-event dinner where she had some car trouble.

Ben, meanwhile, went to the Tom Brady roast … where he delivered a few scathing digs.

His set at the mic was met with mixed reviews … some felt it wasn’t really all that funny — especially when he took aim at internet trolls who talk crap online, calling them a “bitch.”

Anyway … dude’s busy on a Monday, and there’s no time for posing for cameras with wifey.
